Election

i was listening to the radio as i do every morning on the hour drive to school. And i caught the Grace to You broadcast (John McArthur). He was speaking about divine election i think that is the official name, but if you are like me its always interesting to hear about different things that people believe. Before i voice my opinion i would like to give everyone a chance to sound off on what they think if God chooses the "elect" before the foundation of the earth, or whether you think that God knows the choice that we will make i want to hear what people have to say so let me know.
